Hi!
I got a Mac Pro with 4 gb ram. However, when I boot up Vista business the OS only detects 2 gb ram. What could the the cause of this?

vista in a word. The 32 bit version only addresses 2gb of ram.

maybe on a mac but not on a pc, it should at the very least be registering 3Gigs, with SP1 it will state 4Gigs but still register slightly less.

IIRC theres a 2gig limit to the bios emulation, might change with vista sp1 as it has support for efi (mac uses this iirc) as well as the bios.
